Objectives: Curative therapy for hepatocellular carcinoma is liver transplant. To date, the Milan Criteria remain the best pretransplant clinical surrogate for tumor behavior and overall prognosis. Microvascular invasion portends a poor prognosis; however, it is often undetectable before transplant. Furthermore, its pretransplant indicators are not well established. In this study, we investigated the presurgical and pathologic predictors of microvascular invasion in patients with hepatocellular carcinoma.
